This is a very nice, sturdy piece of black tourmaline. It is somewhat rare to see it in this form, because the material can be delicate. There even appears to be shiny mica scattered throughout. This piece stands at about 5" tall. No flaws to note, this is in excellent condition just as it was when I purchased it. Please keep in mind that crystals have natural imperfections, and polished crystals such as this also are not perfect. I always point out if there are true flaws that have developed after I purchased the item. I will be listing a lot more crystals as I have the time, and you can bundle multiple for a better price. I am open to considering all reasonable offers.
